“…Several studies have been carried out related to micropolar fluid. For example, Abbas et al [3] studied the non-orthogonal stagnation point flow towards a stretching sheet. They obtained the solution of coupled ordinary differential equation by using a well-known analytical technique of Homotopy Perturbation Method (HPM) and obtained the results graphically and numerically.…”

Various industrial operations involve frequent heating and cooling of electrical systems. In such circumstances, the development of relevant thermal devices is of extreme importance. During the development of thermal devices, the second law of thermodynamics plays an important role by means of entropy generation. Entropy generation should be reduced significantly for the efficient performance of the devices. The current paper reports an analytical study on micropolar fluid with entropy generation over a stretching surface. The influence of various physical parameters on velocity profile, microrotation profile, and temperature profile is investigated graphically. The impact of thermal radiation, porous medium, magnetic field, and viscous dissipation are also analyzed. Moreover, entropy generation and Bejan number are also illustrated graphically. Furthermore, the governing equations are solved by using HAM and code in MATHEMATICA software. It is concluded from this study that velocity and micro-rotation profile are reduced for higher values of magnetic and vortex viscosity parameter, respectively. For larger values of Eckert number and thermal radiation parameters, Bejan number and entropy generation are increased, respectively. These findings are useful in petroleum industries and engineering designs.

The development of the interface tracking between two immiscible liquids is one of the most challenging problems in fluid dynamics. The simulation of the lubrication process, oil extraction, and the physicochemical mechanism that govern the behavior of the uncertain conduct of interface is a key element in “gas-oil” or “oil-water” natural gas-oil reservoirs systems and should be tracked for optimal recovery. Motivated by the interface evolution process, in this article, an unsteady flow of two immiscible Eringen micropolar and Dusty(fluid-particle suspension) fluids is considered through a horizontal channel. The Analysis of the interface between two immiscible Eringen micropolar and Dusty(fluid-particle suspension) fluids are carried out. Although the channel wall is hyper-stick and no-slip, it is believed that the fluid-fluid interface is unstable and can be also deformed from one location to another; thus, the single momentum equation is coupled for monitoring the interface profiles using the VOF(Volume of fluid) technique. The modeled coupled- partial differential equations are numerically solved by the modified B-spline differential quadrature method. The interface profile under the influence of different parameters, i.e. Froude, Capillary, wave and Reynolds number, volume fraction function, the ratio of viscosities, densities, and time is analyzed through the graph. It is noticed that initially, the vertical elongation of the interface is large, and then the shape of the interface (topology) evolves with time; hence the undulating sequence occurs faster for a more considerable time and eventually becomes stable. The qualitative characteristics of this flow are sustained.

“…The study of non-Newtonian fluid is huge among researchers due to the practical importance especially in industrial processes since in reality most fluids are non-Newtonian. Countless studies of non-Newtonian fluid has been published including the study of micropolar fluid by [1], [2]and [3] and the investigation on boundary layer flow of Jeffrey fluid conducted by [4] and [5]. Casson fluid and viscoelastic fluid are also among the non-Newtonian fluid which has garnered the interest of researchers.…”

Abstract.The main interest of this study is to investigate the effect of MHD on the boundary layer flow and heat transfer of viscoelastic micropolar fluid. Governing equations are transformed into dimensionless form in order to reduce their complexity. Then, the stream function is applied to the dimensionless equations to produce partial differential equations which are then solved numerically using the Keller-box method in Fortran programming. The numerical results are compared to published study to ensure the reliability of present results. The effects of selected physical parameters such as the viscoelastic parameter, K, micropolar parameter, K1 and magnetic parameter, M on the flow and heat transfer are discussed and presented in tabular and graphical form. The findings from this study will be of critical importance in the fields of medicine, chemical as well as industrial processes where magnetic field is involved.
